Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2005-3256 medium priority: Ubuntu including 2 source packages (enigmail, enigmail-mailnews), 8 status rows across 4 suites (dapper, edgy, feisty, upstream): released 5, needs-triage 2, DNE 1.
The key selection dialogue in Enigmail before 0.92.1 can incorrectly select a key with a user ID that does not have additional information, which allows parties with that key to decrypt the message.
